of the arc. It determines how hard the arc
penetrates the metal when the arc is held
short. This is an exceptionally helpful fea-
ture in MMA (SMAW) operation. It helps
hold the molten metal in place in out-of-
position welds by providing a crisp, force-
ful arc. Or, it can provide a soft, buttery
arc that easily washes the metal into the
toes of the weld. This is a matter of opera-
tor preference. Rotating the knob clock-
wise increases dig. There are no recom-
mended settings regarding this feature.
Skill, operating styles and electrode selec-
tion are controlling variables that help de-
termine the optimum setting of the arc
force. Holding the arc close activates the
arc force control and a increase of amps
can be observed. With a little experimenta-
tion, the proper setting can be found for
each task.
9. AC Frequency Control. This control nar-
rows the welding arc and helps to control
penetration and weld shape.

10. AC Balance. This control determines
the amount of time the AC cycle spends in
DCEN (-) or DCEP (+). More DCEN is pre-
ferred for cleaning oxidation, particularly
in aluminum. More DCEP is preferred for
better penetration. A 50% setting equal-
izes the time spent in both. Try this setting
first as a starting point for adjustment.
11. Post Flow. This timer controls the flow
of shielding gas after the weld arc is termi-
nated. Too little post flow time can cause
weld contamination or torch overheating
12. Up Slope. This controls the time that
the machine takes to ramp up the current
from the start current to the normal weld-
ing current. This provides for excellent

control over the welding puddle after it is
developed and allows the operator to ad-
just manipulation techniques as the puddle
warms up.
13. Down Slope. This controls end cycle
of the weld by slowly ramping down the
welding current. As the end of the weld is
reached, the down slope helps prevent
weld cracking and hole formation in the
crater by.
14. TIG/Cut/MMA rocker switch. This
switch allows you to select the use of ei-
ther TIG , plasma cutting or the conven-
tional arc welding features (stick). It is
not recommended to weld with the stick
setup while switched in TIG mode. How-
ever, scratch start TIG welding may be
done in the ARC mode. This discontinues
the HF in sensitive areas. Not all models
are capable of this feature. Be sure to ob-
serve the lower duty cycles of the Arc set-
ting if using TIG in Arc mode.
15. 4T/2T or Remote/Local Rocker
Switch. This switch selects for control
of the TIG weld cycle via the TIG torch
trigger. In the 2T /local mode, simply
touch and hold the trigger to start the
arc and continue holding while welding.
The machine will cycle automatically
according to the settings selected on
the machine. Release the trigger to
finish.
